Original application filed June 23 1906, Serial No. 323,117. Divided and this application ileu'April 15, 1908.-

To alt 'whom 'it lmay concern.'

Be it known that we, ALEXANDER WINTON and HAROLD B. ANDERSON, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Im rovements in the Method of Carburetin ir for Explosive-Engines, of which the fol owing is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in the method of carbureting air for explosive engines, and this application is a division of our pending aplication'led in the United States Patent Hice June 23rd, 1906, bearing It is Well known to those skilled in this art that the explosive mixture for explosion engines is formed by causing the engine to suck air through a carbureting device, thereby forming an explosive mixture, and that the velocity of the air assing through the carbureter varies accorr ing to the speed of By reason of this variation in the air velocity through the carbureter, much difficulty has been encountered in properly carbureting the slowl -moving volumes of air for low speeds of tlie motor, and to prevent an over-rich mixture for the rapidlymoving volumes of air. /f'

Our method consistsy in carbureting the slowly-moving volumes of air by surface carburization, and the rapidly-moving volumes of air by spray carburlzation, which in practice is found to furnish the roper mixture for the various air velocities t rough the carbureting device for the various speeds of the engme;

One of the simplest forms of a paratus for carrying out our improved met lod is illustrated in the accompanying drawings,in which -Figure 1, is a vertical, central, sectional view. Fig. 2, is a cross-sectional view at right angles to Fig. 1.` l

The form of apparatus here shown for racticing our method comprises a casing 1 n which the gasolene is maintained at a predetermined level by meafns of a float 2 within mined level, the controlling valve 4 closes the supply inlet, and the valve is opened beforeA the level of the gasolene appreciably lowers. In this Way the gasolene is maintained at a predetermined level within the chamber 3.

Passing across the chamber 3 is an air passage-Way 6 which is here shown as U-shaped in vertical' section and with its bottom wall in a'plane slightly below the predetermined gasolene level. A gasolene inlet 7 is formed in the bottom Wall of the assage-way 6, at its lowest part, and this in et communicates with the chamber 3. By this construction a a body or puddle of gasolene 8 ismaintained bygravity flow in the bottom of the air passage 6. v A regulating valve 9 cooperates Witlrthe inlet 7 and limits orregulates the rapidity of the flow through this inlet.

This apparatus carries out ,our method by providing a puddle or body of volatile li uid Within the air passage, and the gravity Cil'low of the liquid Within the air passage 1s' reguf lated to maintain this body or puddle of gasolene for slowly-moving volumes of air,`

thereby furnishing surface carburization, but the flow by gravity is not vsuii'icient to supply the Aamount of gasolene necessary for rapidlymoving volumes of air, so that the rapidlymoving volumes of air suck or draw the gasolene through the inlet, causing it to spray,

thus provlding spray carburization for the' rapidly-moving volumes of air.

Having'thus described our invention, wha we claim and desire to secure by Letters .Pat-

1. The method of 'uniformly carbureting volumes of air moving alternately at different velocities, consisting in subjecting the slowly-moving volumes of air to surface contact With a body of volatile liquid, and the rapidly-moving volumes of air to sprayed vo at e i liquid.
